  • the invention relates to a corresponding method for examining a bodily fluid.
  • the test fields are assigned to a respective puncturing element and can be acted upon by body fluid.
  • a test tape device of this kind is from the W02005 / 107596 known.
  • a multi-layer test tape is described in which a lancet-carrying tape strip is sandwiched with a test strip provided with tape strips.
  • the test fields are in fixed positional relation to a capillary groove of the lancets, which supplies the body fluid via a capillary transport.
  • the alignment of the lancets tangentially forward with respect to the direction of tape travel is maintained even with a tape deflection so that the lancet tips describe a relatively large orbit until they have fully retraced the directional change of the tape. Due to the sandwich arrangement, the overall structure is also relatively large.
  • embodiments are still described in which the test fields are arranged alternately to the lancets in the longitudinal spacing on the tape to be actively acted upon by the user after the puncture with a drop of blood.
  • the object of the invention is to further improve the products and methods known in the prior art and to design them in such a way that, in a compact arrangement, simplified handling is possible without elaborate actuation.
  • the invention is based on the idea to avoid a longer flow of the sample from the collecting structure to the test field and instead to actively move the lancing element into a fluidic contact position. Accordingly, the invention proposes that the piercing elements are mounted in each case limitedly movable on the carrier tape via a coupling part, and that a used piercing element by a transfer movement carried out by the piercing element from a use position remote from a test field in a contact position or fluidic connection with a test field can be brought, so that body fluid from the collection structure on the test field immediately exceeded. In this way, the piercing element can be kept very small and reduced to a piercing tip with a collecting volume. The timing of the sample transfer can be precisely determined by means of equipment.
  • the orientation of the piercing elements is reversible relative to the band by the transfer movement, wherein the piercing elements can be aligned at least in the contact position in the longitudinal direction of the carrier tape and by a pivoting movement, in particular Umklapp Gay with an associated test field can be brought into contact.
  • the piercing elements point with their tip transversely to the longitudinal direction of the tape.

  • the piercing elements are covered by a foil or foil bag preferably sterile on the carrier tape, wherein the film or foil bag is firmly connected to the carrier tape and a proximal portion of the respective lancing element.
  • test fields have a reagent layer which is designed for detection of an analyte in the body fluid.
  • Another particularly advantageous embodiment provides that the transfer movement of a puncturing element can be triggered by forward winding of the carrier tape, so that no complex transfer mechanism is required.
  • This can be realized in a simple manner by the fact that the carrier tape is laterally guided past a retaining part, and that the retaining part forms a starting obstacle for a running during the belt transport lancing element preferably for folding over the lancing element.
  • the retaining part is arranged in the region of a deflection point for the carrier tape, wherein the tip of the piercing elements can be lifted off the carrier tape at the deflection point.
  • the lancing elements are clamped at a deflection point for the carrier tape by a holder or a clip for performing a puncturing movement.
  • a further improvement can be achieved in that the deflection point is arranged on a co-moving during the piercing carriage.
  • the carrier tape is guided past a hold-down device formed in particular by a leaf spring, wherein the hold-down device presses a continuous piercing element against a test field.
  • the carrier tape is exchangeable as a disposable item, preferably in the form of a tape cassette.
  • the invention therefore also provides a test tape as disposable for insertion into a test band device according to the invention.
  • the lancing elements are each movably held on the carrier tape via a coupling part, and that the piercing elements are brought by a transfer movement from a remote from a test field use position in a contact position in contact with a test field, so that body fluid is transferred from the collection structure to the test field.

  • the coils 18, 20 are provided in the form of a tape cassette 24 as a consumable. In this way, a tape magazine is provided which allows a variety of tests before a change of consumables is required.
  • the device 10 is designed by a compact hand-held device shown only diagrammatically for a largely automatic measurement procedure.
  • a lancing drive 28 is provided in addition to an acting on the take-up reel 20 belt drive 26.
  • the lancing drive 28 is connected for a linear movement with a carriage 30, which carries the deflection point 22 and a gripper 32 for the piercing element 12.

  • the shaft shaft 42 is aligned in the initial position in the tape running direction of the carrier tape.
  • the lancing elements 12 are each fixed by a film pocket 46 formed from a glued film strip, which ensures a sterile cover and at the same time forms the coupling element in the proximal region of the lancing element.
  • the foil pocket 46 is fixedly connected to the shaft 42 and the carrier band 36 in the rear area.
  • the flexible film pocket 46 thus acts as a film hinge which can be bent around a bending line extending in the transverse direction of the belt in order to allow the lancing element 12 to be folded over against the test field 14.
  • the folding over of the puncturing element 12 serves as a transfer movement in order to permit fluid transfer to an associated test field 14 following on the carrier belt 36 and lying in the swivel range.
  • the control of this movement solely on the basis of the tape advance is based on Fig. 2 easy to understand.
  • the carrier belt 36 is deflected at an acute angle at the deflection roller 22 'in such a way that the tip 40 of a piercing element 12 running over the deflection roller breaks through the foil pocket 46 and is exposed for a skin puncture.
